Introduction
Development of bio-based materials is considered to be an important prospect for Europe. This development
finds its value in the strategic use of resources, in the effort to shift from fossil resources (under depletion
conditions and imported from the global market) to bio-based resources (renewable and sourced in the
domestic market) and in the attempt of reducing the environmental impact of materials and products. Efficient
use of all available resources and responsible utilization of renewable carbon is a way to participate to this
reduction. It is also important to underline that available resources should be preferred also taking into
consideration sustainability and environmental impacts following the life cycle thinking approach. Generally
speaking, the biological origin of a material does not provide a certainty that the material is of low
environmental impact.
CEN/TR 15932 [1] gives recommendations for the terminology and the characterisation of biopolymers and
bioplastics.
The bio-based polymers represent a relevant growing industrial sector. Bio-based polymers are, totally or
partially, based on biomass, namely recently fixed organic matter.
In order to inform users, customers and stakeholders with a transparent and reliable communication about
bio-based polymers, it is important to point out, quantify, and declare the bio-based carbon content.

1 Scope
This Technical Specification provides requirements for the declaration, including statements and labels, of the
bio-based carbon content of items, such as polymers, plastic materials, semi-finished plastic products and
finished plastic products, including composites.
NOTE 1 This document does not override, or in any way change, legally required environmental information, claims or
labelling, or any other applicable legal requirements.
NOTE 2 This document addresses the bio-based content of plastic items, expressed as a fraction of the total organic
carbon content. The declaration of biomass content, i.e. the total amount of raw materials of biogenic origin contained in a
plastics item, expressed as a percentage of the total mass, is out of scope of this document, as there is currently no well
established method to determine the biomass content of polymers or plastics materials.
NOTE 3 Since bio-based polymers can be biodegradable or non-biodegradable, and the origin of the materials
renewable or non-renewable, (see CEN/TR 15932), the declaration of the bio-based carbon content is not an indication of
the biodegradability of an item.

5 Determination of the bio-based carbon content
The polymer or plastic material/product shall be characterised in terms of percentage of the bio-based carbon,
TOC
expressed as a fraction of the total organic carbon content (x ). The bio-based carbon content of the
B
polymer or plastic/product shall be determined according to CEN/TS 16137 provided that the minimum total
organic carbon content is 5 %.
NOTE CEN/TS 16137:2011 is technically equivalent to ASTM D 6866-11 [2]. Though Method A (PSM) of
CEN/TS 16137:2011 is deleted in ASTM D 6866 11 [2], the test results obtained by CEN/TS 16137:2011, Method A, are
considered to be reliable provided that the bio-based carbon content has been determined for an item with a high carbon
fraction.
This document does not take into consideration the content of inorganic carbon (e.g. fillers) which contributes
to the total carbon content of the polymer or plastic material and to fossil CO release in case of incineration.

The bio-based carbon content of the item shall be either determined by testing the item or calculation
according to Equation (1) provided that the bio-based carbon content of each constituent/component have
been determined according to CEN/TS 16137.
